McAfee is wanted for questioning in Belize over the murder of a neighbor. He had been held for a week by immigration officials in Guatemala, where he surfaced after evading Belizean officials for nearly a month.

McAfee -- famous for the anti-virus software that still bears his name -- crossed into Guatemala with his 20-year-old girlfriend to evade authorities in Belize, who want to quiz him as "a person of interest" about the killing of fellow American Gregory Faull.

One of Silicon Valley's first entrepreneurs to build an Internet fortune, McAfee made millions of dollars through antivirus software.

McAfee's behavior has been increasingly erratic in recent years but there is no international arrest warrant for him. Police in Belize say he is not a prime suspect.

The Associated Press and Reuters contributed to this report.

Founder of McAfee security software John McAfee emerged from hiding in Guatemala where he plans to seek asylum. McAfee claims he is being persecuted by police in Belize where he is considered a person of interest in the killing of another American.
